| Abstract: | A new type solid super acid catalyst with the composition of SO4^2-/-TiO2 and added lanthanum was prepared by precipitation and impregnation. The esterification of P - hydroxybenzoic acid and propanol over the catalyst was studied. The influences of preparation conditions on its catalytic properties were studied. The highest esterification yield was exhibited about 94.5%. It showed that this catalyst was reused and regenerated, and excellent one for the synthesis of Nipagin esters. |
